title: Low-grade meningioma showing nearly equal density with spinal fluid on radiographic images.
abstract: A 61-year-old woman had an intracranial tumour that was located on the falx. Meningioma was suspected and the tumour rapidly grew over 1 year. It showed nearly equal density with spinal fluid showing almost no enhancement on radiographic images, like microcystic meningioma. Successful removal of the tumour was achieved. Histopathologically, the tumour was diagnosed as low-grade meningioma. The meningioma had variable sized microcysts and the appearance of solid area was meningothelial meningioma. This is a rare radiographic image for meningothelial meningioma.
